Doon-HINGIJ. i

T 0 @ZZ whom t may concern:

Be it known that I, FRED J. Kon, a citizen of the United States, residing at Toledo, in the county of Lucas `and State 'of Ohio, have invented certain new and useful lmprovements in Door-Hinges, of whichv the following isa specification.

This invention relates to door hinges and is especially designed as an improvement on my prior Patent No. 1282435.'

The purport of this invention is to prot bers arranged in superimposed relation to vide an invisible hinge which will permit the door to be swung completely open into a position parallel with the door-jamb if desired, without shearing the component parts f of the hinge.

A further object of the invention isV to provide a non-shearing hinge which is simple in construction and operation, at the same time, possessing the necessary characteristics of rigidity and durability.

The above and other objects of this invention will be in part described and in part understood from the following description of the present preferred embodiment of the invention,v taken in connection with the accompanying drawings, wherein:

Figure 1, is a top plan view of a hinge constructed in accordance with my invention illustrating its application, the hinge being shown in a closed position.

Fig. 2, is a side elevational view of the hinge illustrating its application, the hinge being shown in anopen position.

Fig. 3, is a top plan view of the device illustrating its application and showing they hinge inan open position.

Fig 4, is a group iigure, showing the hinge casings in perspective.

Fig. 5, is a perspective view of one of the hinge links, and

Fig. 6, is a fragmentary perspective view of a modiiicd form of casing. f

In. the drawings, in order to illustrate the application of this invention, a portion o a door-i amb 6 is shown which has associated therewith a portion of a door 7. The adjacent margins'of the jamb 6 and door 7 are mortised to provide substantially trianular shaped recesses 8 and 9 respectively.

O t3 l l Mounted in each of said mortises is a hinge casing 10, consisting of a metal plate'v thereof reduced to provide beveled mar- Y girls 11. The outer ends of the easngs Specification of Letters Patent. Patented June 28, 1921,

are upturned to provide securing flanges 12 through which screw openings 13 are formed As shown in Fig. 8, the casings are set in the mortises of the jamb and door so that the side 111 of eac-h casing will lie flush with the outer face of the jamb or door with which it is associated. The flanges 12 will be countersunk in the adjacent edges of the jam and door as vshown to advantage in Fig. 2.

vThe hinges consist of a pair of link memprovide upper and lower links 15 and 16 respectively. Each link consists of a substantially L-shape body, the ends of which imityv to the outer margin of the jamb, while the pintle of said upper link 15. which engages the casing of the door?, is arranged remote from the outer margin of the door in proximity to thel inner terminalV of the recess 9. T he lower link 16 is conversely arranged in said casings as illustrated to advantage in Figs. 1 and 3. Suitable recesses 19 are formed in the casings 10 to receive theknuckles 17. Each link has a circular enlargement 20 formed thereon which will be in superimposed relation when the links are assembled. These enlargements may, or may not be, equipped with a pintle as desired. However, the provision of these enlargements will prevent shearing of the links and will likewise facilitate initial movement of the door whether the latter be f in an open or a closed position. Furthermore, the manner of formation of the pintles 18 and the method of associating them with the hinge casings 10 will likewise tend to prevent shearing of the hinges.

It is tobe understood thatthe conguration of these links may be altered to conform to the shape of doors used, without departing from the spirit and scope of this invention. y

In Fig. 6 a' slightly'modiied form of cais- .ing is shown, In this form the wall of each `pressure of the hinges in veryV great. By

each of which has one endpivoted to the door and the other end pivoted to the doorA forming the rib in the special manner shown, the rcost of manufacture will be reduced to a minimum.

VVhat'fis claimed is:

l. A door hinge including inflexible links jamie, each link being unconnected .at any other point in its length, said links being substantially L shape to permit opening of the door to a position parallel with the door jamb. l f

2. Av door hinge including casings mounted inthe adjacent margins of the door and door-j amb, a pair of links, one ol which has one of its ends pivoted in the inner terminal o''t the door-j amb casing and its opposite end pivotal'ly mounted in the outer end of the door casing, the other end ofisaid link being arranged subjaoent the first link and pivotally Vmounted in said casings in a manner converse to the manner of mounting the irst said link, said links being arranged in superposed relation but not connected,

and co-acting means on said links to prevent shearing thereof. n

3. A door hinge including caslngs mount- *edV in the door, each casing having its side wall pinched inwardly to provide a longitudinally extending reinforcing rib, a pair olf links, one of whichis pivoted in the casing above said rib and the other pivoted in the casing below then rib substantially as described. y l Y Y 'Inv testimony whereof I aix my signature in presence of two witnesses.
